SPECIFICATION forming part of Letters Patent No. 401,963, dated April23, 1889.

Application filed February 4, 1889.

To all whom it may con/cern:

Be it known that I, ROBERT B. McCoN- NELL, of Paducah, in the county ofMcCracken and State of Kentucky, have invented certain new and usefulImprovements in Roofing- Tongs; and I do hereby declare the following tobe a full, clear, and exact description of the invention, such as willenable others skilled in the art to which it appertains to make and usethe same.

My invention relates to an improvement in rooiing-tongs, the object ofthe same being to provide grips with adjustable gage-plates securedthereto, so that the edges of sheet metal can be readily turned tovarious sizes.

A further object is to provide a device of the above character whichshall be simple and economical in construction and durable and efficientin use; and with these ends in view Vmy invention consists in thecertain features of construction and combinations of parts, as will beherein after fully described, and pointed out in t-he claim.-

In the accompanying drawings, Figure 1 is a perspective view of theinvention. Fig. '2 is a top plan view with the handles'vertical, andFig. 3 is a vertical sectional view of the tongs.

A and B represent the lower ends of the tongs, to which are secured theblades C and D, respectively. The blade C is secured in a verticalposition relatively to the handles E thereof, and is provided with thecircularshaped recesses F, formed near each end thereof. Each recess isadapted to receive the gage-plates Gr, each of which is adjust SerialNo. 298,614. (No model.)

ably secured therein by means of the bolts H, rigidly secured to thebacks of the plates and passing through the lower blade, C, to whichthey are adjustably secured by means of the jaw-nuts I. The plates G areprovided with the spurs K, adjacent to their edges. The gage-plates areadjusted by slackening the jaw-nuts I.Y The plates can then be rotatedand the spurs K brought to or from the front edges of the blades at anydistance to correspond with the size of the edge desired to be turned onthe tin, which varies from one-half to two and one -half inches. Thenuts are then screwed up to lock the plates in adjusted y position. Theupper blade, D, is set at right angles to the blade C for the purpose ofpermitting the free movement of the gage-plates and spurs.

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

In a gripping device, the combination, with the lower blade havingcircular recesses formed therein and gage-plates having an eccentricprojection adj ustably secured therein, of an upper blade adapted t'oengage said lower blade, substantially as shown and described.

In testimony whereof I have signed this specification in the presence oftwo subscribing witnesses.
